This is probably the best game I've played so far, and that includes the game I worked on haha! Tonnes of levels for a jam game, all of the necessary elements were there and functioned without issue. There were some nice QoL touches, like the variable speed buttons and the programming bar re-ordering instructions when dragging-and-dropping into another slot.
I see a lot of people talking about level 17, but I actually found that one fairly easy; I definitely took longer on a previous level (maybe 9, can't remember now) and I stopped playing on 19 (only because I'd seen enough to comment and there's a lot of games to get through!).
Something I think a lot of games miss, particularly game jam games, is levels that introduce new concepts in an easy but interactive way (ours definitely did because the levels were rushed...). I thought you did an excellent job with this and it's subtle and often goes unnoticed, so I'd thought I'd point it out.
If I was to be picky, my only suggestions would be to sort the spelling/grammar (totally appreciate the time constraints and the fact English may not be your native language), add some more tracks and make it possible to click on an instruction to add it to the next available slot in the programming bar. Other than that and some more content, you've pretty much got a production-ready game imo.
Awesome work, and I hope this gets the ratings it deserves!!
